A foot support 1 is mounted on two parallel frame members 2, 3 in which are pivotally mounted the legs 18, 19 of the support 16. The braking member 10 comprises a wheel engaging portion 11 of channel section each side wall of which is pivoted to one of the frames members 2, 3. A pedal portion 14 of the brake member extends over the foot support 1 and a spring 15 acts under compression to urge the wheel engaging portion 11 away from the wheel. Hooks 22 on the portions 11 have arcuate slots 23 which receive a ground engaging part 17 of the support 16 to retain the latter in the raised position. The slots are of sufficient length to allow the hooks 22 to slide on the part 17 when the brake is operated. When the support 16 is swung into or out of the raised position the portion 17 engages cam surfaces 24, 25 respectively on the hooks 22 and causes the brake to pivot away from the wheel to permit the portion 17 to enter or leave the slots 23. During this pivotal movement the spring 15 is under tension and will thus retain the support 16 in the slots when the brake member swings back. Forward movement of the support 16 when in the ground engaging position is limited by shoulders 21 on the support engaging the tubes 2, 3.

Title: Improvements in or relating to time-division multiplex telecommunications exchange systems
IPC: H04Q11/04
Filed: 1966-01-13
Abstract: 1,122,273. Automatic exchange systems. SIEMENS A.G. 13 Jan., 1966 [14 Jan., 1965], No. 1556/66. Heading H4K. In a T.D.M. exchange (particularly a PBX) having at least one circulating memory containing address data for operating subscribers' speech switches, the number of time slots used in the memory for storing data exceeds the number of time slots used in the system for interconnecting subscribers. Thus the addresses of the calling and called parties may be stored in successive pulse phases (time slots) in the memory and their appearances then used to prime the corresponding line gates, the actual opening of the gates being controlled by a pulse in the immediately succeeding pulse phase or by means of pulses generated by a timing pulse generator. In the case of a conference call, the conferees' addresses emanate at phases uxa, uxb, uxc and trigger bi-stable circuits Q1, Q2 and Q3 respectively. At phase uxd, all the triggered circuits are reset and, in so being, cause gates S1 S2 and S3 to open whereby communication between Tn1 Tn2 and Tn3 via highway SM occurs. Interim calls may be set up in similar manner. In another arrangement (Fig. 5, not shown) separate memories are used for the addresses of the calling and called parties. Each address circulates in one time slot and on its appearance it applies a pulse to a pulse lengthening circuit hich opens the line gate for a period approximating to two such time slots. The time slot following each address is used for holding data relevant thereto, e.g. a metering count. At the end of the call the address is applied to a print-out mechanism to which the metering count then existing is applied, under the control of diverters Qa, Qz, Qb, Qd, in the second time slot. The possibility of metering subscribers not connected to this exchange by means of this double time slot allocation is discussed. The bi-stable circuits Q1 may comprise a rectangular loop core driving a transistor (Fig. 4, not shown). The memories are preferably constituted by delay lines. The reduction in the number of memories required is made possible since the pulse length and interval required for data storage is considerably less than the pulse length and interval required for definite and unique speech switch operation. The highway may be earthed during the time slots not allocated to switching purposes.
